    • Connect your phone to your PC via cable USB ;
    • Remember to accept the RSA key by flagging them off as soon as you see the message on the phone;
    • Go to the directory folder Fastboot / ADB , hold the "key Shift ", click with the right button of themouse and then again click " Open Command Window Here ";
    • To test the connection to the device (must appear the S / N ), the terminal window you just opened, type: adb devices
    • Start the mode bootloader or fastboot . To do this, you can run the command code, while the device is connected to the PC: adb reboot bootloader
    • Now, the ZUK Z2 is not recognized as a device, you must specify the ' id OEM . The code is "-i 0x2b4c ", any command fastboot must be suffixed with the following code: -i 0x2b4c

    • Now, go to this site:
    http://developer.zuk.com/bootloader

    • Place your SN and add two zeros "00" at the end , then wait for the email from ZUK. Check SPAM and other folders as required incase it does not hit your inbox.
    [​IMG][​IMG]

    • Copy the files unlock_bootloader.img in adb directory
    • Now type the command for unlocking:
    fastboot -i 0x2b4c flash unlock unlock_bootloader.img

    • Once you get the confirmation message, you have to type the following command ( which will format your internal memory ):
    fastboot -i 0x2b4c oem unlock-go

    • You can disconnect the cable USB

    Special note about serial:

    IF serial number is 6 digits add 00 at the end.

    IF serial number is 7 digits add 0 at the end.

    IF serial number is 8 digits you do not need to add any other digits to the end.

    Cheers,

    Mark

    have you installed custom recovery (twrp)? cause my question is: do we get further updates while using a custom recovery? or do we still get them via OTA but can't install it cause of twrp? And do I even receive further updates while rooting / installing supersu?

    Hi, there's a typo in OP:

    <fastboot oem unlock 0x2b4c -i-go>
    should be <fastboot -i 0x2b4c oem unlock-go>

    I'm unable to register at developer.zuk.com, no matter what email I try (private, work, wife ...) I always get "Input error..."
    Anyone else having this issue?
